Difficulty has changed. Our profit will fall?
Difficulty drop equals more coins which equals more or equal profit most of the time. Difficulty rise equals less coins. However block reward is slowly decreasing so you'll be getting less coins overtime and less profit but that corresponds to price of coin.
I was making before changing daily 1.2 million. Current 500,000 seems. Fine?
The question is who's getting the other 0.7 million?
Assuming we still have the same number of miners with the same proportions of hashrate.
Uh no one is getting the extra .7 mill doesn't even make sense. This is how increasing nfactor scrypt jane algorithm works. Eventually difficulty will decrease to a point were you will be receiving a little less coins than you were with nfactor 10 since block reward is steadily decreasing.
